Performance / Core Web Vitals, how do they compare?

Compare representative pages and buying journeys with the intended storefront, images, scripts and integrations. Where field data is available, assess LCP, INP and CLS across the relevant audience; use lab tests for repeatable diagnosis. A hosted engine, CDN or frontend framework cannot establish the result of an untested implementation. Record the measurement conditions and test account-specific B2B flows as well as public product pages. No platform-wide speed benchmark is asserted here.
